feat(todo): Settings choose the app's appearance and language

Browse source 
The developer asked for Todo to offer what Learn's Settings offer first
(ADR 0014's amendment of 4 Nov 2026). Todo passed a fixed look, the
system's theme and language; it now opens halkyon_app's LookCubit on
<app support>/look.json in main, provides it above InstanceGate, and its
start screens and each person's MaterialApp follow it. Settings show
DeviceLookCard right after the Sync and operator's cards, as Learn's,
offering English (UK), English (US) and Deutsch (todoLanguages).

Whats-New: Settings: choose the app's appearance and language.
Whats-New-De: Einstellungen: Darstellung und Sprache der App wählen.
